I'm using SSTP on RUT955. It worked fine in RUT9XX_R_00.05.04 but after a firmware update to RUT9XX_R_00.06.00, VPN is not established. It seems the router doesn't even try to connect.
I’ve already reset the device to factory defaults and reconfigured from scratch. Unfortunately, without success.
After a downgrade to RUT9XX_R_00.05.04 the SSTP VPN connection is functional again.
Any idea how to solve this?
